The V02 Max 100 is an enigma; it is just as comfortable on the trail for training sessions as it is competing in skate marathons. This is the end result of combining an ultra light K2 Softboot with the revolutionary Vortech Ventilation System and the best bearings and biggest wheel set up in the X-Training line. This is the perfect choice for skaters interested in generating the speeds of a training skate, without giving up the support found in a fitness skate.
